Instructions
Priority Mail
Measure the record sleeve for the 45 using the tape measure. Write down the measurement. Fold the priority box as flat as possible. Using the ruler, draw a square on the flattened box that's at least 1/2 inch larger than the record sleeve.
Insert the 45 into its sleeve. Wrap the sleeve carefully in a double layer of tissue paper or craft paper. Insert the wrapped record into the flattened, cut box. Tape the open ends of the box closed using the packaging tape.
Address the package. Write "Fragile, do not bend" in a readily-noticeable location on the box. Send the package using priority mail.
Regular Mail
Place one piece of cardboard atop the other. Using the ruler, draw a square on the cardboard at least 1/2 inch larger than the record sleeve. Cut along the lines using the craft knife and the ruler. Cut the bottom piece of cardboard so it matches the top piece.
Place the record into the sleeve, then wrap the sleeve in a double layer of craft paper or tissue paper. Place the wrapped record between the layers of the cardboard "sandwich." Tape the open ends of the package securely with packaging tape.
Write "Fragile: do not bend" on the front of the package. Address the package and mail it.
